Exercise is essential for maintaining good health, and there are a few simple workouts that every man should be doing to stay in shape. These exercises are easy to do and don't require any special equipment, making them perfect for those who are just getting started with their fitness journey.

1. Push-ups: Push-ups are a classic exercise that work the chest, shoulders, and triceps. To do a push-up, start in a plank position with your hands placed slightly wider than shoulder-width apart. Lower your body down until your chest is just above the ground, then push back up to the starting position. Aim for 3 sets of 10-15 reps.
2. Squats: Squats are a great exercise for working the legs and glutes. To do a squat, stand with your feet shoulder-width apart and your hands out in front of you. Lower your body down as if you were sitting back in a chair, keeping your back straight and your knees behind your toes. Push back up to the starting position. Aim for 3 sets of 10-15 reps.
3. Pull-ups: Pull-ups are a great exercise for working the back and biceps. To do a pull-up, grab a pull-up bar with an overhand grip and hang from the bar with your arms fully extended. Pull your body up towards the bar until your chin is above the bar. Lower yourself back down to the starting position. Aim for 3 sets of 10-15 reps.
4. Planks: Planks are a great exercise for working the core. To do a plank, start in a push-up position with your hands placed slightly wider than shoulder-width apart. Hold your body in a straight line from your head to your toes for 30-60 seconds. Aim for 3 sets.
5. Lunges: Lunges are a great exercise for working the legs and glutes. To do a lunge, stand with your feet hip-width apart and step forward with one foot. Lower your body down until your thigh is parallel to the ground and your knee is directly above your ankle. Push back up to the starting position. Aim for 3 sets of 10-15 reps on each leg.

These exercises are a great starting point for building a strong and healthy body. Remember to start with a weight that is comfortable for you and gradually increase the weight and reps as you get stronger. It's also important to stretch before and after your workout to prevent injury and improve flexibility.

In addition to these exercises, make sure to get plenty of rest and eat a healthy diet. Consuming enough protein to support muscle recovery and repair is important. Avoid processed foods and sugars, focus on consuming lean proteins, fruits, vegetables, and healthy fats.

Finally, always consult a physician before starting any new exercise program. They will be able to assess your health and give you guidance on how to get started safely.
